Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Good evening and welcome to JustAnswer!!
The buzzing is the lock actuator which means it's bad. The lock actuator is serviced in the complete latch assembly. But the proper way to diagnose your issues is to see what codes are in the PSDM(Power Sliding Door Module) then run the diagnostics for each code to determine the issue. We see a lot of wires being damaged in the track that lays in the lower section in the loom, so you may want to check them and see..
I hope this helps,
